> Use cgroup to get container resource utilization

> Key: YARN-6668
> URL: https://issues.apache.org/jira/browse/YARN-6668
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager
> Affects Versions: 3.0.0-alpha3
> Reporter: Haibo Chen
> Assignee: Miklos Szegedi
>
> Container Monitor relies on proc file system to get container resource
> utilization, which is not as efficient as reading cgroup accounting. We
> should in NM, when cgroup is enabled, read cgroup stats instead.
